Seems fairly common for a coach to cite match fitness when a player goes out on a month's loan. Jukes said the same about Ridyard, and we'll be reminded on Saturday of how that ended.
Purtill will have had a week's training to judge Baldwinson's fitness. If he's fit to play he should be in the team, though wouldn't want to say who for. If Mason is fit, then he'll be replacing Dezaria from the 17 that played Salford.
